Iím hoping someone here can point me in the right direction of how I can solve two (small) issues with the cabin fan system in my momís 1988 Toyota pickup.
When I turn the cabin fan on, leaves/fir needles/etc. come out of the air vents into the cabin. I had a similar problem with my 4Runner, and I ended up just needing to clean a mouse nest out of the blower fan. Iíve removed the leaf debris that was in the pickupís blower fan, but thereís still a lot (!) of stuff coming out of the air vents when I turn the fan on, especially when switched from recirculation to outside air.
Iím guessing all this debris is probably originating near the air intake, but I havenít found a diagram of where the air intake is for the cabin fan system, and if itís different than the air intake for the motor. (Incidentally, there was a small mouse nest beneath the engine air filter, so Iím thinking mice could be to blame for this issue.) I do have a copy of the book How to Keep Your Toyota Pickup Alive for the Compleat Idiot (which is appropriate for my skill level
) and the 1988 Toyota Truck and 4Runner Repair Manual, and itís possible that Iím just looking in the wrong places for info.
The second issue is that the lever for adjusting the temperature on the cabin fan/heating system seems to be jammed at about the midpoint, and thereís occasionally a rattling sound from that area when the truck is moving. (Hopefully not another mouse issue?) Would I be able to access this area if I take apart the dash, or is the box containing the controls for the fan system totally sealed?
Any advice regarding how to fix these issues will be greatly appreciated! (Including pointing me to a thread that I missed when searching on this topic
) Thank you!
